Apprendre à voir, apprendre à dire

open access: yesArts et Savoirs, 2017
The emergence of a microscopic science in the 18th century was marked by an attempt to standardize the methods of observation and also of description. How can these methods be shared?

Inference of Historical Population-Size Changes with Allele-Frequency Data

open access: yesG3: Genes, Genomes, Genetics, 2020
With up to millions of nearly neutral polymorphisms now being routinely sampled in population-genomic surveys, it is possible to estimate the site-frequency spectrum of such sites with high precision.

The importance of calcium in improving resistance of Daphnia to Microcystis. [PDF]

open access: yesPLoS ONE, 2017
Changing environmental calcium (Ca) and rising cyanobacterial blooms in lake habitats could strongly reduce Daphnia growth and survival. Here, we assessed the effects of maternal Ca in Daphnia on transfer of resistance to their offspring against ...

Successfully resisting a pathogen is rarely costly in Daphnia magna [PDF]

open access: yes, 2010
Background A central hypothesis in the evolutionary ecology of parasitism is that trade-offs exist between resistance to parasites and other fitness components such as fecundity, growth, survival, and predator avoidance, or resistance to other parasites.

Evaluation of Possible Causes of Non-Predatory Mortality of Crustacean Zooplankton in a Small Siberian Reservoir [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2008
Non-predatory specific mortality (NPSM) of dominant zooplankton species, Daphnia (longispina group) and Cyclops vicinus, was estimated during 1997-2000 sampling seasons on the basis of a new direct method: live/dead sorting and sediment trap measurements.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...
